The Ancestor Of All Land Plants
Red seaweeds fossils date back 1.05 billion years ago, but previously no green seaweeds had been found of similar ages. Molecular clocks suggest the first green photosynthesizing plants appeared somewhere between 1,600 and 720 million years ago, but scientists find such a wide range unsatisfying and hope fossil discoveries will narrow it down.
The discovery raises the question of why green seaweeds took so long to move onto dry land, given the speed with which they adapted to most environments once they did.
